SPEGIFTCA'IION forming part of Letters Patent No. 436,401, dated September 16,1890;

length of several nails, so that by one cut' through the plate a corresponding number of spearheaded nails are produced.

Referring to the accompanying drawing, the figure represents a nail-blank plate for making nails with spear-heads embodying my invention.

The width of the plate is equal to the length of several nails, and the two surfaces are rolled to the form shown-that is, so as to form the bodies cl of the nails, which at their upper ends are depressed to form notches e, and then again enlarged to form the spearheads f. The portions a, that are intended to form the points, are not quite separated from 0 the p01 tions 1), that are to form the heads of the next adjacent nails, so that when passed through a shearing-machine a certain length of the plate (equal to the width of the nail re quired) is cut oif, which strip can then be sepa rated at the junction of the points a and heads I), (by a tumbler or other means,) and form a number of separate and independent spear-headed nails, although only one out has been made from the plate. The nails when thus cut and separated appear as shown at E. The main body at of the nail is intended to be driven into the heel of the boot and the spearhead f left projecting, and upon which the upper lift is forced and there held by the notch e under the spear-head. If desired, the plate might be cut up into strips first and then into nails.

What I claim as my invention is- A nail-blank plate the two end edges of which represent the form of spear-headed nails, substantially as shown and described.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 15th day of April, A. D. 1889.
